Illustration 42
Illustration 42 is a representation of the label that will
be installed next to the fuel filler cap on the fuel tank
of the application.
The fuel specifications that are listed in the table 10
are released as acceptable to use on all 1200 series
of engine.

Fuel Specification
EN590
"ASTM D975 GRADE 1D S15"
"ASTM D975 GRADE 2D S15"
"JIS K2204"
"BS 2869: 2010 CLASS A2 or EU equivalent"
(1) All the fuels must comply with the specification in the table for the Perkins Specification Distillate Diesel Fuel.
Diesel Fuel Characteristics
Cetane Number
Fuel that has a high cetane number will give a shorter
ignition delay. A high cetane number will produce a
better ignition quality. Cetane numbers are derived
for fuels against proportions of cetane and
heptamethylnonane in the standard CFR engine.
Refer to "ISO 5165" for the test method.
Cetane numbers more than 45 are normally expected
from current diesel fuel. However, a cetane number
of 40 may be experienced in some territories. The
United States of America is one of the territories that
can have a low cetane value. A minimum cetane
value of 40 is required during average starting
conditions. A fuel with higher cetane number is
recommended for operations at high altitudes or in
cold-weather operations.

Comments
European Automotive Diesel Fuel (DERV)
"North American Light Distillate Diesel fuel with less than 15 PPM sul-
fur level"
"North American Middle Distillate general-purpose Diesel fuel with less
than 15 PPM sulfur level"
"Japanese Diesel Fuel" Must meet the requirements that are stated in
the section "Lubricity".
"EU Off-Road Diesel fuel. Acceptable from 2011 MUST have less than
10 PPM sulfur level"
Fuel with a low cetane number can be the root cause
of problems during a cold start.
Viscosity
Viscosity is the property of a liquid of offering
resistance to shear or flow. Viscosity decreases with
increasing temperature. This decrease in viscosity
follows a logarithmic relationship for normal fossil
fuel. The common reference is to kinematic viscosity.
Kinematic viscosity is the quotient of the dynamic
viscosity that is divided by the density. The
determination of kinematic viscosity is normally by
readings from gravity flow viscometers at standard
temperatures. Refer to "ISO 3104" for the test
method.
